这意味着DB2按顺序在表空间上提取每一个数据页面到缓冲池。
This means that DB2 fetches every data page in the table space sequentially into the buffer pool.
FETCH节点使用这些 RID来定位表空间内的对应数据页面。
These RIDs are used by the FETCH node to position the corresponding data pages in the table space.
但是要注意，内联会极大增加数据页面的行大小，从而减少每个页面的行数量。
Note, however, that inlining significantly increases the row size on your data pages. This in turn decreases the number of rows per page.
数据页面的内容包括页面上的数据和有关页面上数据的信息(有时称为元数据)。
The content of a data page is both the data and information about the data on the page (sometimes called metadata).
这是因为，LOB这样的XML文档体积庞大，无法放到表数据页面的单个行中。
This is because XML documents, like LOBs, can be too large to fit within a single row on a data page of the table.
区段确定如何跨越多个容器进行数据分段，并确保一个容器里的数据页面是连续的。
Extents determine how data is striped across multiple containers and ensure that the data pages in a container are contiguous.
在db2缓冲池中数据页面也保持压缩的，为了潜在的重用允许更多的数据缓存在内存中。
A data page also remains compressed in the DB2 buffer pool there by allowing more data to be cached in memory for potential reuse.
通过dms表空间，DB2更加可以控制如何将数据页面物理映射到称作区段的磁盘空间分组中。
With DMS tablespaces, DB2 has more control over how data pages are physically mapped in disk space groupings known as extents.
然后通过FETCH节点获取合格的RID以提取来自表格空间的相应记录和数据页面到db2缓冲池。
The qualifying RIDs are then taken by the fetch node to fetch the corresponding records and data pages from the table space into the DB2 buffer pool.
使用Ajax，您可以确保当一个新数据页面正在被提取时，用户不必观看整个页面重载，而是只使用新数据集替代部分页面。
With Ajax, you can ensure that the user doesn't have to watch the entire page reload when a new page of data is being fetched, but instead just replace part of the page with the new set of data.
现在数据量比以前大得多，而且有时系统看上去已经崩溃了，但事实上只是一个页面跳转到另一个页面花的时间较长而已。
There's a lot more data now and it sometimes seems the system has crashed but, in fact, it just takes ages to go from one screen to the next.
既然我们已创建了我们的第一个JSF表单，我们就将需要把控件绑定到页面数据。
Now that we have created our first JSF form, we need to bind the controls to page data.

At this point, you might wonder how to get the description data to render in the page.
门户模型表示门户用于生成门户页面的数据。
Portal models represent the data that the portal USES to produce a portal page.
用户界面定义如何将数据模型实例并入页面的表示。
The user interface defines how the data models instance is incorporated into the presentation of the page.
如果数据是像页面那样被静态加载的，这不成问题。
That's not a problem when the data is loaded in a static way, as this page is.
依赖于您的数据库内存大小，可以在此处理过程中取代其它的用于引导业务流程的数据库页面。
Depending on your database memory size, other database pages that are used for navigation of business processes might get displaced during this processing.
然而，我们却不得不从 HTML页面获取数据。
So, instead, we were required to scrape HTML pages for our data.
最后，调用查询现有记录和用数据更新html页面的函数。
Lastly, the functions that query the existing records and populate the HTML page with the data are called.
查找图中显示异常的页面数据。
通常，当前页面上的数据请求是基于前一个页面中的响应数据的。
Often, the data request on the current page is based on the response data from previous pages.
当然，我们并不想彻底失去移出此页面的数据。
Of course, you don't want to lose the data from this page altogether - yet.
不再把实例数据写入页面，而是从服务器异步检索数据然后将其动态增加到页面模型中。
Instead of writing the instance data to the page, you'll retrieve it asynchronously from the server and then dynamically add it to the model on the page.
“假”数据不能代表真实数据在页面上会占据的空间。
"Fake" data doesn't represent the actual space on the page that would be taken up by realistic data.
数据块页面存储模型中的最小存储实体。
Data blocks Pages Smallest storage entity in the storage model.
从HTML页面提取数据。
示例Portlet：访问页面元数据。
分析系统，例如Coremetrics，收集和处理数据，允许页面和portlet视图报告，以及特殊portlet业务事件报告。
Analytics systems, such as Coremetrics, gather and process the data, allowing the reporting of page and portlet views and of specific portlet business events.
